📋 About This Mod
Note that lots of Overhauls have already started to use this optimization directly.
But it should never hurt to have this mod installed (worst case it does nothing).
This mod will re-compress any LZMA unity3d resource to use LZ4 compression for faster load times.
The LZ4 format will probably use 20% to 80% more diskspace than LZMA compression.
But it is virtually free in terms of decompression, while LZMA adds a significant overhead there.
LZMA decompression is slow at maybe 20MB/s, while LZ4 will go up to 5GB/s.
Reports indicated good results on Undead Legacy, Darkness Falls and other overhauls.
Note that in the future those mods will probably use that LZ4 "speed" trick directly.
Until then, this mod can optimize assets bundles for overhauls and single mods.
Please Note that on first run, the optimizer will make the game unresponsive.
Give it a few minutes in order to finish the optimization step.
And EAC must be disabled in order for it to work.
Mod is proven to be able to optimize DF and UL assets/resources.
Apparently it (unexpectedly) also helps dedicated server startup times.
Currently the optimizer will keep the original unity3d files for safety measures.
Once you've verified everything is working correctly, you can remove "*.org" files.
To do that, bring up the console (press F1) and enter `optimizer cleanup`.
